USB Features
USB bus can provide power to low-power electronic devices. Olympus EVOLT E-510 10MP Bus-power and power isolation, and has very good stability. However, the available current is limited, while the host or power between the load and there is a potential interoperability problems.
Two-way USB port from 90? differential shielded twisted-pair, VBUS (+5 V power supply), and constituted. This is four lines from the aluminum foil and braid shield within the outer shield layer shielding. The latest USB specification version 2.0 standard is available from USB organizations for free. To achieve full compliance with the normative standards, through a functional device and the host controller to achieve two-way communication between the. Specification defines a unit load as 100mA (max). Any equipment allowed to draw the maximum current of 5 units of the load.
USB ports can be divided into low-power port and power port into two categories, low-power port can provide a unit load of current, high-power port provides up to five units of the load current. When the device is connected to the USB port, the device enumeration process to identify and determine its load requirements. In this process, only to allow the device from the host draw up a unit load of current. Enumeration process is complete, if the host's power management software allows, then the high-power devices can draw a larger current.
Some host systems (including downstream USB hub) through fuses or active current limit detector provides workflow features. If the USB device is not USB port through the enumeration process begins with drawing large currents (more than one unit load), then the host will detect over-current condition and will be closed are using one or more USB ports. The market supply of a number of USB devices, including independent Olympus EVOLT battery charger, do not function controller to handle enumeration process, but the current draw is more than 100mA. In this inappropriate conditions, these devices may cause the host problem. For example, if a drawing 500mA current device into a bus-powered USB hub, and did not correct the enumeration process, it may lead to the hub port and host port at the same time overload.
The host operating system, using advanced power management of the situation will be even more complicated, especially notebook computers, it is always hoped that the port currents as low as possible. In some power-saving mode, the computer will suspend issuing commands to the USB device and then think that equipment into a low-power mode. Equipment can be included in a function to communicate with the host controller is always a good practice, even for the same is true for low-power devices.
USB 2.0 specification is very comprehensive and provides for the quality of power supply, connectors, construction, cable material, allowing the voltage drop and inrush current. Low current and high-current power supply port with a different target. This was mainly by the host and the load between the connectors and cable voltage drop on the decision, and includes USB-powered hub to generate voltage drop. Including computer, or self-powered USB hub, including the host, have large current port, which provides maximum 500mA of current. Passive, bus-powered USB hub with a low current port. Table 1 shows the high current and low-current USB ports upstream side (power) pin allows the voltage tolerance.
These indicators apply to the upstream end of the host or hub port connector pins. Cables and connectors on the I x R drops need to be considered separately.
Subject to the host USB 2.0 specification, high-power port with the upstream end of 120?F, low ESR capacitors. The connected USB device input capacitance of 10?F or less limited to, in the initial stage of the load connected, allowing the load from the host (or self-powered hub) to draw the maximum charge number of 50?C. As a result, when the new device is connected to the USB port, the upstream port transient voltage drop is less than 0.5V. If the normal work load required a greater input capacitance, you must provide inrush current limiter, in order to ensure a larger capacitor charging current does not exceed 100mA.
When the USB port with a bus-powered USB hub, hub on the access of low-power device, USB port on a permissible DC voltage drop shown in Figure 1. High-power loads and bus-powered hub connection, the voltage drop will exceed the target given in Figure 1, and will cause the bus overload.
Figure 1. Host to low-power load voltage drop is greater than the figure given to allow DC voltage drop, it will cause the bus overload.
Help answer the question about Olympus EVOLT E-510 10MP
Olympus Evolt E-510?
My passion for photography began a little over a year ago with my Sony Cybershot DSC-W100. I feel like this simple point-and-shoot (with automatic everything) is suppressing my creative abilities that photography is all about. I'm just a 16 photographer Olympus EVOLT E-510 10MP but now that I have began getting job offers, I am looking to upgrade to a professional DSLR. After some research, I've become fond of the Olympus Evolt E-510. Although I am a firm believer that the photographer makes the picture, not the camera, I do want something professional to work with for the sake of my (future) customers. So, what I'm getting to - is the Olympus Evolt E-510 a good professional camera (why or why not) and do you have a better recomendation within or around the same price range? Thanks!

I’m still learning how this camera works [just so much to do on it!] but i using it everyday. love it!!
I absolutely love this camera. Having purchased it this fall, I have been able to use it for a variety of activities, including anything ranging from sports photography to still life photos. All in all, it is an excellent camera, leaving me with no regrets in my purchase choice.
This is a great item, i had previously owned the rebel xti by canon, it was a good camera , but the e-510 is overall better. I know you are reading this review to see if the camera is for you. If your a begginer who plans to buy this camera and not have to buy alot of additional lenses and accesories, this is the camera for you. Why? because it has all the features that you will ever need without having to buy any exoensive additional accesories.
Not much to say other than the camera takes great pictures. Very easy to use, fits great in my hands. I like Olympus Cameras.
I’ve owned an E-410 for over a year. I like shooting handheld macro with my Olympus 70-300 lense. The big difference between the 410 and 510 is image stabilization. The E-510 seems to gain about 3 stops at 300mm, quite useful for handheld macro shooting! For the price, it would be tough to find a digital dslr with more semi-pro specs and features.
I’ve been using a Point-and-Shoot camera for years now, and I felt that I maxed out its potential. Sure, landscape photography is nice, but i’ve always been a wildlife guy & trying to be a wildlife photographer with a point-and-shoot isn’t going to get you good results. It was at this point that I decided I wanted an SLR w/ interchangable lenses. I chose the Olympus E-420 because it was within my price range and list of features.
I’ve been learning and using this camera for a few months now, and I am very happy with the results. Coupled with a telephoto lens, my wildlife photography collection now includes over 60+ bird species in my area.
I would recommend this camera to someone looking to get a SLR camera. The price is great and Olympus Zuiko lenses are very cost friendly.
I also have an e-510 body, but have been exclusively been using the 420 since I got it. Really like the size, but still has all the great features. I got the 25mm pancake lens with it and will keep this combo in the bag along with the lenses I use with the e-510. Super fun little camera – the e420 became a keeper right off the bat!!
The Olympus E-420 is a great camera for the price. It operates well and I would definitely suggest this camera for anyone looking into photography, or just for personal uses.
I love this camera!!!! I bought a Nikon all manual camera when I was in the service overseas and back some years sold the camera to get a video camera!!! Big mistake! I looked for a new manual film recently and decided to go digital. That was my best decision. I researched all the digital cameras and compared price and features and I decided on the olympus. This was an even bigger good decision. The camera is fast, no lag time for shutter to actually take the picture. I love the rapid multi picture feature. It snaps pics one after another with no lag time!!!! I love it! The most important feature is the picture itself, they are very sharp and excellent detail in macro mode. I take pics of flowers close up and they look like pictures in photography magazines. I looked at the nikon D40 and thought this was a better camera. The lens is excellent!!!
You can’t go wrong with this camera. i did manual film for years and this is so much better and has the ability to do all manual if you like. The menus are very good. I love the camera!!!!!
I chose the E-420 over similar offerings from Canon and Nikon because this camera just felt better in my hands. Small, light weight, no big old grip on the right side of the camera. All these reasons are really personal preferences as you really have to get technical to see the differences in image quality; which there are. But if you are like me, shoot a lot of images, print a few 4 X 6s and fewer 8 X 10s, store your pictures on your computer and email pictures to family and friends now and then, the E-420 will serve you well. Do I need to tell you that you should purchase from amazon.com? I didn’t think so.

Shot a lady’s tennis tournament today and the E-420 with 40 to 150 mm lens performed very well. Out of over 300 shots, only 4 were out of focus. The 4 bad shots were the first images in continuous shot sequences. Once I figured this out and pre focused prior to shooting, the problem went away. Just used the sport mode and let the camera figure out the settings.

I started my DSLR experience with the E-510, while this was a quirky little camera that needed cajoling to perform well, the E-520 is nothing like that. After a year with the E-510, I ended up replacing it with the E-520 and what an improvement this camera is! A lot of quirks that the E-510 had (blown highlights, excessive contrast, bad LCD, underexposed mid-tones in JPEG) had been remedied in the E-520 and to add to that a bunch of newer features had been added as well. The most notable ones (for me) are:
1. Imager AF in live-view with face detection.
2. IS mode 3 for vertical panning.
3. Bigger and brighter and a more accurate LCD.
4. And by far the best addition, remote flash triggering for up to 3 groups!
It’s amazing that Olympus could offer so much in a so-called “beginner” level camera and to think Nikon doesn’t even offer live-view view! This is one of the biggest reasons for me to stick to Olympus as they don’t skimp on features even in lower-level bodies.
I have no hesitation in recommending this camera for the first time DSLR buyer as well as a pro looking for a back up body for the E-3. Although compact, it’s very nicely built and has a superior and much better build quality than the E-500 as well as similar Canon offerings.
I had the two kit lenses but sold the 14-42mm lens and kept the 40-150mm lens. I’m simply amazed with this lens as it offers an effective 300mm focal length in the smallest package currently in the market. I took the E-520 along with this lens to a recent U2 concert and the guards didn’t even stop me as they couldn’t tell what this lens was capable of by looking at its size! I ended up getting some stunning images with this camera and lens combo.
Last, but not the least, I would like to talk about IQ; Olympus has sorted out the tone curve in the E-520 and its MUCH better than the E-510 and allows amazing pictures straight out of the camera. I have no qualms using this camera all the way up to ISO 800, although at ISO 1600 the noise is higher than average and in some cases one will also notice banding in the shadows. I normally switch to B&W for ISO 1600 and that makes all the difference. However, in a pinch you can get some excellent ISO 1600 colour images as well if you’re willing to shoot RAW and carefully process. This is about the only “minus” in this camera that I can think of.
Overall, this is an excellent camera and gives an excellent bang for the buck and I highly recommend it!
I have been an Olympus Camera user since I bought my OM-1 over 30 years ago. My first digital camera was the C-3030 camera which provided great use for over 8 years while living aboard my sailboat in the Caribbean. It was a natural choice to move up to the e-520 as I have a large collection of OM lens and wanted to use them on the new DSLR. The camera has a feel very similar to the C3030 in both menu and general feel. After receiving the camera I was really impressed with the quality of the images, both vibrant and great resolution. Although the original OM lens won’t give me auto-focus, this has proved to be a minor problem as I am used to the full manual functions of the OM-1. The quality of the pictures using the OM lens has been extraordinary. If you are looking for a camera that gives you a lot of bang for the buck I would highly recommend you consider it.
This is my 28th digital camera and I love it. I had the Canon SXI for a short while and it was good but did not impress me. This SLR does impress me. It is wonderful for scenic work and for studio work. It is the best buy in a dSLR by far.
Just went by the reviews on Amazon and the more expensive model of the same lineage. I am quite pleased with the speed and quality of pictures. Hunts a bit in low light, but the colors in the picture are quite good. Overall, a good buy for the money and an easy picture taker.
I purchased the Olympus E-520 about 6 months ago after researching cameras for about 3 months. I looked at the Pentax K200D, Canon XSI, Nikon D40, Nikon D40x, Nikon D60, Sony Alpha 300 as well as the Olympus E-420 and the Olympus E-510.
I read all sorts of detailed reviews ([...] has some of the best ones), watched video reviews and product demonstrations on YouTube, spoke to friends and family that owned some of the cameras mentioned above and most importanty, I went to camera stores and actually held (and worked with) the cameras in my hands.
This is my first DSLR camera and compared to the competition, I’m very happy with my selection. I wound up buying the camera body with the 2 kit lenses. Originally I planned to only buy the body and then either the 14-54mm or 12-60mm higher end Olympus lenses but I decided that having two (lower quality) lenses would give me a nice range to work with as I learn different techniques. Also I like to take pictures outdoors and am very happy with the pictures I’ve taken so far. This is not to say that I haven’t taken great pictures at night or indoors, I have and I will say that you can too but you have to learn how to use the camera. I took loads of horrible pictures at first, lucky for me, my dad (who owns the Sony Alpha 300 and has been taking beautiful photos with SLRs for years) helped me to understand that most of my bad pictures were my fault and not the camera.
I’d also like to recommend a book or series of books, “The Digital Photography Book,” written by Scott Kelby. In this series Scott tells you exactly how to acheive a various effect without really explaining the theory behind it. He will say something like if you want to get that silky warerfall or stream effect this is what you need to do: Switch your camera to Shutter priority mode, an set the shutter speed to 1 or 2 seconds. To avoid getting a picture that is blown out (because of all the light your slow shutter speed is letting in) it is best to shoot around sunrise or around sunset. Since the shutter is open for 1 or 2 seconds use a tripod. Since the water is moving it will be blurry and the surrounding area will be sharp.
Books like the one mentioned above will help you to realize that there is a lot you can do with your camera if you only take the time to learn.
I read all of these Amazon reviews months ago and really like how people can comment on a someone’s review and I recommend that you check out the comments that appear on 1 and 2 star product reviews, sometimes the comments reveal that the user incorrectly reviewed a product and that is helpful to know!
All of the cameras above take good pictures. It’s important to feel comfortable navigating the camera menus, you should feel comfortable holding and taking pictures with the camera and you should think about what you’ll be using the camera for.
I actually just purchased the Olympus MF-1 OM Lens Adapter ($82 on amazon), which allowed me to buy an old Olympus OM 50mm f 1.8 prime lens. Good glass will help me take better pictures and this adapter helped me to get a good quality lens for a ridiculously cheap price (I got the OM 50mm f 1.8 prime on ebay for $20).
The more I use my E-520, the more I love it. I’m learning so much and appreciating all that Olympus packed into this lovely camera. You can check out to pictures that I submitted in online photo contests ([...]) by clicking on the following link:
